    To improve the ice-breaking properties when sailing ahead and astern, the hull (10) of a ship with the maximum width of the ice-breaking water line formed in the fore-body and with devices for trimming and ballasting in the stern area (12) is designed so as to be widened in its part above the ice-breaking water line (1) to such an extent that, if the after-body (12) sinks due to trimming or ballasting of the ship when sailing astern, a channel is broken in the ice sheet, which channel is wider than the wide fore-body part (11), which passes this channel when sailing astern. …<IMAGE>…

    The invention relates to shipbuilding, in particular to icebreaking vessels.
    The aim of the invention is to increase the effectiveness of the destruction of ice both during the forward course in the circulation mode and in the reverse course,
    Figure 1 shows an icebreaking vessel with a designated normal icebreaker waterline, non-differentiated icebreaking waterline and lowered icebreaking waterline, side view; figure 2 - the waterline of the famous icebreaking vessels with various forms of the bow of the vessel, views from above; on FIG. 3 - an icebreaking vessel with a designated normal le, an extension waterline and a non-diffused icebreaking waterline, a view; side view | figure 4 - the same, when moving forward with a normal ice-breaking water; lines, top view; figure 5 is the same, i when moving backward when a non-differentiated waterline; Fig. 6 is the same, I for circulating movement, forward to ice with side ledges on the ship's landing strip on the back portion of the vessel for splitting ice} in Fig. 7 - top view propeller screw.
    In FIGS. 1-7, the following notation is adopted: position 1 denotes nor-; the waterline is the smallest, position 2 is the direction of movement of the icebreaking vessel,
    position 3.1 - non-differentiated E icebreaker waterline, position 3.2 - omitted icebreaker waterline with ledges on the side of the back of the ship's hull
    4d splitting ice and position
    5- obtained by the action of the ledges 4 ice floes. The icebreaking vessel contains the hull 6 of the vessel, the front part of which is indicated by the position 7, and its rear part - by the position 8, the bow of the vessel is indicated by the position 9.
    Figures 1 and 2 show a growing improvement in the splitting power of ice from the waterline of form a through the waterline of form b to the waterline of form B, which is the best form of the waterline of known vessel hull structures. FIGS. 3-5 illustrate the process of a well-known ice-breaking vessel shown at the beginning; : splitting ice when moving forward / red (Fig. 4) with normal icebreaker wat; Line 1 and when moving on.
    the backside (FIG. 3) with an ice-free waterline 3.1 that is not differentiated, it is obvious that when moving forward in an ice sheet a smoothly cut, ice-free passage is formed and even approximately rectangular ice floes 10 that go evenly to the side. non-broken ice cover and removed from the propeller propeller zone. When moving backward with the stern lowered to the waterline 3.1, a passage is formed in the ice, which allows for the passage of the widest part of the hull of the cutting edges on the bow in the passage made.
    With known icebreaking vessels, deficiencies are eliminated during the exportation

     The rear part 8 of the hull 6 of the icebreaker ship is provided with ledges.
    4 for splitting ice, which are made on both sides of the hull 6 of the vessel in the area of the rear part of the vessel's crush. The maximum width of the nifoxod obtained by means of 0 steps 4 is larger than the maximum width of the front part of the vessel, so that with the help of the ledges or the corresponding ledges with non-diffracting rear part 8 of the vessel, another expansion passage and lowering circulation are carried out ice splitting process. The rear part 8 of the vessel (FIG. 6) may have a greater width than the width of the front part 7 of the vessel. The sections 11 and 12 of the waterline in the area of the rear part of the vessel 8 are transferred to the protruding sides. in the expanding portions 13, so that the 5 waterlines of the rear part 8 of the vessel have an approximately petal-like expansion, however, the design of the rear part of the vessel may have a more ruddy shape than shown in FIG. Transitions of the side portions 11 and 12 of the ship in the zone of the portions 13 may go straight into a partially elliptical profile, however, for hydrodynamic reasons, it is preferable to provide arcuate portions that have the action of a sliding surface. The design of the rear part 8 of the icebreaking vessel (Fig. 6) is especially
